'app'ncation med :raaary'fia 192e. seien Nef 612,51 A I i Be it known that l, HARRY (i. Generis', a citizen of the United States, residing. Pittsburfrh, in the county, of'fillegheny and yState ofbPennsylvania, have inventeda new and useful Improvement in a Flushing Cuspidor, of which the vfollowing is a specification.

` This invention relates toV afflushing cuspidor and constitutes an improvement upon the device .of my prior Patent-No. 67 8,481, dated July 16, 1901, i Y

The device shown in the prior patent noted above is so .arranged that the bowl of the cuspidor liesbelow the level of the floor in which the cuspidor isset. bowl, adjacent the upper extremity thereof, isa perforated Hushing ring connectedwith l.al water supplyv pipe. A drainpipe .connects direct-ly withthe lower. extremity of the bowl; the Vbowl itself is in theV form .of an approximately regular inverted cone;

and no appreciableV portion of the bowl eX- .tends above thev level of the floor in which` .itisset` Y Oneobject of the present invention is to provide a flushing cuspidor havingv a bowl set permanently below the level of the floor and a removable top disposed above the floor flevel, but positioned on said bowl andarrangedto empty thereinto. v .l f f Another object ofthe inventionisto provide a flushing ring so arranged that it may be swung upwardly out of the bowl of the -cuspidor so that, when so desired, vthe cus- `pidor may be utilized as a drain in washing the floor in which it isset. Y

Y A further object'of the invention is to provide in combination .with a cuspidor having an outlet arranged-'to permit the retention of water therein a flushing or lifting jet vso arranged that in Vflushing the cuspidor such. jetV sweeps from the cuspidor water standing in the bowl thereof.

In the accompanying drawings Figure 1 is a vertical sectional view through a cuspidor forming the subject matter of the invention showing tion; YFigure Q .is a fragnaentarfVV sectional view showingfhe cuspidor with the flushingV ring thereof raised to permit use of theV cuspidor as a drain.; Figure is an enlarged KView, half plan and half V,horizontal section, of the vflushing ring andi-.ts connections; Figure 4 is a vertical section through'the Within the y vwith a plurality ofsprayi'ng apertures 17, which may be arranged in staggered relation the same installed-in posi? same; sectional view of the bowl of thefcuspidor.

and Figure Sis venlarged.:vertical Y ienne The bowl 1 of the cnspidor'iaasshown in Figurel` ofthe drawings, set .with its. up-

per extremity substantially level with the VThis bowl is' upper surfaceV of a' floor 2a. preferably Vformed as an integral casting and comprises a main orfbody portion 1a and a discharge or. outlet portion 1b, being in the general form of a gooseneck to provide a trap for the bowl. Extending circumferentially of the upper extremity of the latter the bowl 1 is a flange 2, whichr has thereon Y vertically disposed lugs 3 for positioning the top member or cover 4 of the cuspidor.

' Leading totheeuspidor is a water line 5, .which branches at the 'lf-connection` 6 to Vprovide a vertical flushing conduit 7 anda horizontal Vflushing conduit 8. Of these the branch conduit 7 leads to the flushing ring 9, which is pivotally lmounted interiorly of the bowl 1'V adjacent the upper extremity thereof.

The structure of the flushing ring 9 and themountingtherefor comprise a fitting 10, which passes bowl 1 .and isscrew threaded ina coupling 12 on the supply conduit?. The fitting lO lis preferablyv formed as an integral casting, and is coveredto provide' an interior duct or water passagelpassing Vupwardly therethrough. The flushing ring 91s, not contin. nous, but is formed with agap or aperture, providing extremities 14 for connection to the fitting I,10. This connection is effected by means of screw threaded collars 15 carried by the ring9 to 'engagefextension 16 of the fitting 10 leaving the ring 91 free to turn in the fitting. I The ring 9 itself is provided on the' under side of the 'ring -or may be otherwise, arranged to insure a satisfactory distribution of :fine'jets of water. A lug 18, which may be integral withthe body of the through an aperture 11 yin the bowl as shown, acts as asupport and .positive stop for the flushing ring 9 when the ring is l in its. operative flushing positionshown in Y Vlligurel of the drawings,

In flushing the cuspidor, water flowing by way of supplypipe `5 passes through the branch 7,-fand fitting y10, and issues from ring 9 through yapertures w1'? Ilin the form of fine jets directed against of the bowl `l'of theucuspidor.: Simultane-` 'A the inner surface body of bowl l outwardly through the disrcharge portion lb thereof,

Lifting jet i9 is shown as cast integral' with the bowl l, and has an extension screwthreaded to the 'lf-connection 6. lt is cored to provide a duct 20, an extended duct or chamber 2l, and a constricted passage or duct 22. lt should be observed that the passage22 is directed inwardly and upwardly of` the bowl l in such manner that the column of water issuing therefrom is aimed directly at the discharge portion lb of the bowl, and that it does not strike any portion of the inner surface of the bowl.

ln normal use of the cuspidor it is fiushed at regular intervals, as at the close of a working day. ln such flushing the jets from the flushing rin g 9 carry down froml the sides of the body la of" the bowl any particles which may have adhered thereto, and thoroughly cleanse this portion of the bowl.

Simultaneously the column ofwater from lifting jet -19 sweeps out through discharge portion lb water collected in the bowl to"- gether with refuse which has collected, or which is swept down into the body of the bowl. y l

lf the cuspidor is to be used as a drain in washing the floor 2, the flushing ring is swung upwardly'to a position at approximately right'anglesto the floor, as shown invFigure 2 of the drawings. ln this position the ring is clear of the bowl, so that it cannot catch land retainv refuse swept orwashed intoithe -bowl from the iioor 2a. Y ln this position, further, the flushing of the cuspidor may discharge upon V`the floorY jets of water fromthe apertures 17 or ring 9, to assist in the cleansing operation.k y j The flushing cuspidor as illustrated and described above is particularly well adapted for use in ofiice `buildinor the workrooms of factories, andthe like. In such use a number of cuspidors may desirably be connected Vwith a single source of water supply, and

the flow of water for iiushing the cuspidors may alsoI if desired be made automatic. Such arrangement,v however, is. not illustrated or described herein as it constitutes merely an indicated use of the subject matter of the present inventio l What I claim is: n j v l. A fiushing cuspidor comprising a bowl arranged to be disposed below the level of a floor, a stationary fitting in the wall of Vvs aid bowl and having a duct extendingtherethrough, a water supply conduit connected to said fitting, a hollow flushing ring so supportedV in said fitting that'it may be swung into a positioncjoncentric with the interior surface of saidbowl or swung upwardly therebeyond, lugs extending vertically upward from saidV bowl", and av removable cover vmember arranged vto beV positioned on the bowl by said lugs.
